For short single commands, prefer one-liners:

* `for` with the Zsh syntax: `for x (foo bar) print ${x}`

* Short `if` form: `if [[ -d ${dir} ]] cd ${dir}` (Only applicable when the test part is delimited, such as by `[[ ]]` or `(( ))`. See the [Zsh manual](http://zsh.sourceforge.net/Doc/Release/Shell-Grammar.html#Alternate-Forms-For-Complex-Commands).)
